Schplitter thanks for the try and I'll still hook you up on a frag!
Thanks Reggae, twinpeaks, big casino, and nano for the help! You all have some frags due just let me know what you like.
I'm still comptemplating the closed loop holes. Or maybe using the second set of holes in the overflow. Take them up about half way and 90 degree turn them and out the side of the overflow. Then combine the two as a closed loop intake. I'd bring both the return and the closed loop return manifold over the back anyway. That would just require 2 holes in acrylic overflows vs. having to drill the back of the tank.
